Reno, Nevada (CNN) — “Mass casualties” were reported at an air show after a plane slammed into the box seat area in front of a grandstand at the National Championship Air Races and Air Show in Reno on Friday, a spokesman for the show told CNN.

At least two people died and 54 people were transported from the scene with injuries, according to officials.

The pilot, identified as Jimmy Leeward, a real estate developer from Ocala, Florida, was likely killed in the crash, the show said in a statement. He was flying a P-51 Mustang. The event has been canceled and a memorial service will be held for the pilot Saturday afternoon, the show said.

A Reno hospital said Friday night on its website that it had received a “total of 25 patients” after the plane crashed. It said two people, one male and one female, had died.
